In hybridcombinations, PHF1J demonstrates high grain yield, strong drydown,excellent seedling emergence, above average late season plant health andstalk strength.

The inbred has shown uniformity and stability within the limits ofenvironmental influence for all the traits as described in the VarietyDescription Information (Table 1, found at the end of the section). Theinbred has been self-pollinated and ear-rowed a sufficient number ofgenerations with careful attention paid to uniformity of plant type toensure the homozygosity and phenotypic stability necessary for use incommercial hybrid seed production. The line has been increased both byhand and in isolated fields with continued observation for uniformity.No variant traits have been observed or are expected in PHF1J.

Inbred maize line PHF1J, being substantially homozygous, can bereproduced by planting seeds of the line, growing the resulting maizeplants under self-pollinating or sib-pollinating conditions withadequate isolation, and harvesting the resulting seed using techniquesfamiliar to the agricultural arts.

Genotypic Characteristics of PHF1J

In addition to phenotypic observations, a plant can also be identifiedby its genotype. The genotype of a plant can be characterized through agenetic marker profile, which can identify plants of the same variety ora related variety, or be used to determine or validate a pedigree. TheSSR profile of Inbred PHF1J can be found in Table 2 at the end of thissection. As a result of inbreeding, PHF1J is substantially homozygous.This homozygosity has been characterized at the loci shown in the markerprofile provided herein. An F1 hybrid made with PHF1J would comprise themarker profile of PHF1J shown herein. This is because an F1 hybrid isthe sum of its inbred parents, e.g., if one inbred parent is homozygousfor allele x at a particular locus, and the other inbred parent ishomozygous for allele y at that locus, the F1 hybrid will be x.y(heterozygous) at that locus. The profile can therefore be used toidentify hybrids comprising PHF1J as a parent, since such hybrids willcomprise two sets of alleles, one set of which will be from PHF1J. Thedetermination of the male set of alleles and the female set of allelesmay be made by profiling the hybrid and the pericarp of the hybrid seed,which is composed of maternal parent cells. One way to obtain thepaternal parent profile is to subtract the pericarp profile from thehybrid profile.

Subsequent generations of progeny produced by selection and breeding areexpected to be of genotype x (homozygous), y (homozygous), or x.y(heterozygous) for these locus positions. When the F1 plant is used toproduce an inbred, the resulting inbred should be either x or y for thatallele. In that regard, a unique allele or combination of alleles uniqueto that inbred can be used to identify progeny plants that retain thoseunique alleles or combinations of alleles.

Therefore, in accordance with the above, an embodiment of this inventionis a PHF1J progeny maize plant or plant part that is a first generation(F1) hybrid maize plant comprising two sets of alleles, wherein one setof the alleles is the same as PHF1J at all of the SSR loci listed inTable 2. A maize cell wherein one set of the alleles is the same asPHF1J at all of the SSR loci listed in Table 2 is also an embodiment ofthe invention. This maize cell may be a part of a hybrid seed, plant orplant part produced by crossing PHF1J with another inbred maize plant.

Genetic marker profiles can be obtained by techniques such asRestriction Fragment Length Polymorphisms (RFLPs), Randomly AmplifiedPolymorphic DNAs (RAPDs), Arbitrarily Primed Polymerase Chain Reaction(AP-PCR), DNA Amplification Fingerprinting (DAF), Sequence CharacterizedAmplified Regions (SCARs), Amplified Fragment Length Polymorphisms(AFLPs), Simple Sequence Repeats (SSRs) which are also referred to asMicrosatellites, and Single Nucleotide Polymorphisms (SNPs). Forexample, see Berry, Don et al., “Assessing Probability of Ancestry UsingSimple Sequence Repeat Profiles: Applications to Maize Hybrids andInbreds”, Genetics, 2002, 161:813-824, and Berry, Don et al., “AssessingProbability of Ancestry Using Simple Sequence Repeat Profiles:Applications to Maize Inbred Lines and Soybean Varieties”, Genetics,2003, 165: 331-342.

Particular markers used for these purposes are not limited to the set ofmarkers disclosed herein, but may include any type of marker and markerprofile which provides a means of distinguishing varieties. In additionto being used for identification of Inbred maize line PHF1J, a hybridproduced through the use of PHF1J, and the identification orverification of pedigree for progeny plants produced through the use ofPHF1J, the genetic marker profile is also useful in further breeding andin developing an introgressed trait conversion of PHF1J.

Means of performing genetic marker profiles using SSR polymorphisms arewell known in the art. SSRs are genetic markers based on polymorphismsin repeated nucleotide sequences, such as microsatellites. A markersystem based on SSRs can be highly informative in linkage analysisrelative to other marker systems in that multiple alleles may bepresent. Another advantage of this type of marker is that, through useof flanking primers, detection of SSRs can be achieved, for example, bythe polymerase chain reaction (PCR), thereby eliminating the need forlabor-intensive Southern hybridization. The PCR detection is done by useof two oligonucleotide primers flanking the polymorphic segment ofrepetitive DNA. Repeated cycles of heat denaturation of the DNA followedby annealing of the primers to their complementary sequences at lowtemperatures, and extension of the annealed primers with DNA polymerase,comprise the major part of the methodology.

Following amplification, markers can be scored by electrophoresis of theamplification products. Scoring of marker genotype is based on the sizeof the amplified fragment, which may be measured by the number of basepairs of the fragment. While variation in the primer used or inlaboratory procedures can affect the reported fragment size, relativevalues should remain constant regardless of the specific primer orlaboratory used. When comparing lines it is preferable if all SSRprofiles are performed in the same lab. The SSR analyses reported hereinwere conducted in-house at Pioneer Hi-Bred. An SSR service is availableto the public on a contractual basis by DNA Landmarks inSaint-Jean-sur-Richelieu, Quebec, Canada.

Primers used for the SSRs reported herein are publicly available and maybe found in the Maize GDB on the World Wide Web at maizegdb.org(sponsored by the USDA Agricultural Research Service), in Sharopova etal. (Plant Mol. Biol. 48(5-6):463-481), Lee et al. (Plant Mol. Biol.48(5-6); 453-461), or may be constructed from sequences if reportedherein. Primers may be constructed from publicly available sequenceinformation. Some marker information may also be available from DNALandmarks.

Map information is provided by bin number as reported in the Maize GDBfor the IBM 2 and/or IBM 2 Neighbors maps. The bin number digits to theleft of decimal point represent the chromosome on which such marker islocated, and the digits to the right of the decimal represent thelocation on such chromosome. A bin number.xx designation indicates thatthe bin location on that chromosome is not known. Map positions are alsoavailable on the Maize GDB for a variety of different mappingpopulations.

PHF1J and its plant parts can be identified through a molecular markerprofile. An inbred corn plant cell having the SSR genetic marker profileshown in Table 2 is an embodiment of the invention. Such plant cell maybe either diploid or haploid.

Also encompassed within the scope of the invention are plants and plantparts substantially benefiting from the use of PHF1J in theirdevelopment, such as PHF1J comprising a introgressed trait throughbackcross conversion or transformation, and which may be identified byhaving an SSR molecular marker profile with a high percent identity toPHF1J, such as at least 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%,89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5% identity.Likewise, percent similarity at these percentages may be used toidentify hybrid and other non-inbred plants produced by the use ofPHF1J.

An embodiment of this invention is an inbred PHF1J progeny maize plantor plant part comprising the same homozygous alleles as the plant orplant part of PHF1J for at least 90% of the SSR loci listed in Table 2.A plant cell comprising the same homozygous alleles as a plant cell ofPHF1J for at least 90% of the SSR loci listed in Table 2 is also anembodiment of this invention. In these specific embodiments, 90% mayalso be replaced by any integer or partial integer percent of 80% orgreater as listed above. One means of producing such a progeny plant,plant part or cell is through the backcrossing and/or transformationmethods described herein.

Similarly, an embodiment of this invention is a PHF1J progeny maizeplant or plant part comprising at least one allele per locus that is thesame allele as the plant or plant part of PHF1J for at least 90% of theSSR loci listed in Table 2. This progeny plant may be a hybrid. Aprogeny or hybrid plant cell wherein at least one allele per locus thatis the same allele as the plant cell PHF1J for at least 90% of the SSRloci listed in Table 2 is also a specific embodiment of this invention.In these specific embodiments, 90% may also be replaced by any integerpercent listed above. One means of producing such a progeny or hybridplant, plant part or cell is through the backcrossing and/ortransformation methods described herein.

In addition, the SSR profile of PHF1J also can be used to identifyessentially derived varieties and other progeny lines developed from theuse of PHF1J, as well as cells and other plant parts thereof. Progenyplants and plant parts produced using PHF1J may be identified by havinga molecular marker profile of at least 25%, 30%, 35%, 40%, 45%, 50%,55%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%,73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%,87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% or 99.5%genetic contribution from inbred line PHF1J, as measured by eitherpercent identity or percent similarity.

Comparing PHF1J to Other Inbreds

A breeder uses various methods to help determine which plants should beselected from segregating populations and ultimately which inbred lineswill be used to develop hybrids for commercialization. In addition toknowledge of the germplasm and plant genetics, a part of the selectionprocess is dependent on experimental design coupled with the use ofstatistical analysis. Experimental design and statistical analysis areused to help determine which plants, which family of plants, and finallywhich inbred lines and hybrid combinations are significantly better ordifferent for one or more traits of interest. Experimental designmethods are used to assess error so that differences between two inbredlines or two hybrid lines can be more accurately evaluated. Statisticalanalysis includes the calculation of mean values, determination of thestatistical significance of the sources of variation, and thecalculation of the appropriate variance components. Either a five or aone percent significance level is customarily used to determine whethera difference that occurs for a given trait is real or due to theenvironment or experimental error. One of ordinary skill in the art ofplant breeding would know how to evaluate the traits of two plantvarieties to determine if there is no significant difference between thetwo traits expressed by those varieties. For example, see Fehr, Walt,Principles of Cultivar Development, p. 261-286 (1987). Mean trait valuesmay be used to determine whether trait differences are significant.Trait values should preferably be measured on plants grown under thesame environmental conditions, and environmental conditions should beappropriate for the traits or traits being evaluated. Sufficientselection pressure should be present for optimum measurement of traitsof interest such as herbicide, insect or disease resistance. Similarly,an introgressed trait conversion of PHF1J for resistance, such asherbicide resistance, should not be compared to PHF1J in the presence ofthe herbicide when comparing non-resistance related traits such as plantheight and yield.

In Table 3, data from traits and characteristics of inbred maize linePHF1J per se are given and compared to other maize inbred lines andhybrids. The following are the results of these comparisons. The resultsin Table 3 show inbred PHF1J has significantly different traits comparedto other maize inbred lines.

The results in Table 3A compare inbred PHF1J to inbred PH5TG. Theresults show inbred PHF1J has significantly different yield, moisture,early stand count, pollen weight, plant height, and percent of barrenplants compared to PH5TG.

The results in Table 3B compare inbred PHF1J to inbred PHAA0. Theresults show inbred PHF1J differs significantly over multiple traitsincluding yield, moisture, early stand count, tassel size and percent ofbarren plants when compared to inbred PHAA0.

The results in Table 3C compare inbred PHF1J to inbred PH0AV. Theresults show inbred PHF1J differs significantly from PHOAV in a numberof traits including early growth, number of growing degree unitsrequired for 50% of the plants to be shedding pollen, and tassel size.

Development of Maize Hybrids using PHF1J

A single cross maize hybrid results from the cross of two inbred lines,each of which has a genotype that complements the genotype of the other.The hybrid progeny of the first generation is designated F1. In thedevelopment of commercial hybrids in a maize plant breeding program,only the F1 hybrid plants are sought. F1 hybrids are more vigorous thantheir inbred parents. This hybrid vigor, or heterosis, can be manifestedin many polygenic traits, including increased vegetative growth andincreased yield.

PHF1J may be used to produce hybrid maize. One such embodiment is themethod of crossing inbred maize line PHF1J with another maize plant,such as a different maize inbred line, to form a first generation F1hybrid seed. The first generation F1 hybrid seed, plant and plant partproduced by this method is an embodiment of the invention. The firstgeneration F1 seed, plant and plant part will comprise an essentiallycomplete set of the alleles of inbred line PHF1J. One of ordinary skillin the art can utilize either breeder books or molecular methods toidentify a particular F1 hybrid plant produced using inbred line PHF1J.Further, one of ordinary skill in the art may also produce F1 hybridswith transgenic, male sterile and/or backcross conversions of inbredline PHF1J

The development of a maize hybrid in a maize plant breeding programinvolves three steps: (1) the selection of plants from various germplasmpools for initial breeding crosses; (2) the selfing of the selectedplants from the breeding crosses for several generations to produce aseries of inbred lines, such as PHF1J, which, although different fromeach other, breed true and are highly uniform; and (3) crossing theselected inbred lines with different inbred lines to produce thehybrids. During the inbreeding process in maize, the vigor of the linesdecreases, and so one would not be likely to use PHF1J directly toproduce grain. However, vigor is restored when PHF1J is crossed to adifferent inbred line to produce a commercial F1 hybrid. An importantconsequence of the homozygosity and homogeneity of the inbred line isthat the hybrid between a defined pair of inbreds may be reproducedindefinitely as long as the homogeneity of the inbred parents ismaintained.

PHF1J may be used to produce a single cross hybrid, a double crosshybrid, or a three-way hybrid. A single cross hybrid is produced whentwo inbred lines are crossed to produce the F1 progeny. A double crosshybrid is produced from four inbred lines crossed in pairs (A×B and C×D)and then the two F1 hybrids are crossed again (A×B)×(C×D). A three-waycross hybrid is produced from three inbred lines where two of the inbredlines are crossed (A×B) and then the resulting F1 hybrid is crossed withthe third inbred (A×B)×C. In each case, pericarp tissue from the femaleparent will be a part of and protect the hybrid seed.

Combining Ability of PHF1J

Combining ability of a line, as well as the performance of the line perse, is a factor in the selection of improved maize inbreds. Combiningability refers to a line's contribution as a parent when crossed withother lines to form hybrids. The hybrids formed for the purpose ofselecting superior lines may be referred to as test crosses, and includecomparisons to other hybrid varieties grown in the same environment(same cross, location and time of planting). One way of measuringcombining ability is by using values based in part on the overall meanof a number of test crosses weighted by number of experiment andlocation combinations in which the hybrid combinations occurs. The meanmay be adjusted to remove environmental effects and known geneticrelationships among the lines.

General combining ability provides an overall score for the inbred overa large number of test crosses. Specific combining ability providesinformation on hybrid combinations formed by PHF1J and a specific inbredparent. A line such as PHF1J which exhibits good general combiningability may be used in a large number of hybrid combinations.

A general combining ability report for inbred PHF1J is provided in Table4. This data represents the overall mean value for these traits overhundreds of test crosses. Table 4 demonstrates that inbred PHF1J showsgood general combining ability for hybrid production.

Hybrid Comparisons

These hybrid comparisons represent specific hybrid crosses with PHF1Jand a comparison of these specific hybrids with other hybrids withfavorable characteristics. These comparisons illustrate the goodspecific combining ability of PHF1J.

The results in Table 5 compare a specific hybrid for which inbred PHF1Jis a parent with other hybrids. The results show that inbred PHF1J showsgood specific combining ability.

The data in Table 6 show that numerous species of the genus of F1hybrids created with PHF1J have been reduced to practice. Phenotypicdata are presented for these hybrids and are based on replicated fieldtrials. Of course, many more species of this genus may be created by oneof ordinary skill in the art without undue experimentation by crossingPHF1J with a multitude of publicly available inbred lines. For example,see J. T. Gerdes et al., Compilation of North American Maize BreedingGermplasm, pp. 1-87 (Crop Science Society of America, 1993) which isincorporated by reference for this purpose.

Introgression of a New Locus or Trait into PHF1J

PHF1J represents a new base genetic line into which a new locus or traitmay be introgressed. Direct transformation and backcrossing representtwo important methods that can be used to accomplish such anintrogression. The term backcross conversion and single locus conversionare used interchangeably to designate the product of a backcrossingprogram.

Backcross Conversions of PHF1J

A backcross conversion of PHF1J occurs when DNA sequences are introducedthrough backcrossing (Hallauer et al. in Corn and Corn Improvement,Sprague and Dudley, Third Ed. 1998), with PHF1J utilized as therecurrent parent. Both naturally occurring and transgenic DNA sequencesmay be introduced through backcrossing techniques. A backcrossconversion may produce a plant with a trait or locus conversion in atleast one or more backcrosses, including at least 2 crosses, at least 3crosses, at least 4 crosses, at least 5 crosses and the like. Molecularmarker assisted breeding or selection may be utilized to reduce thenumber of backcrosses necessary to achieve the backcross conversion. Forexample, see Openshaw, S. J. et al., Marker-assisted Selection inBackcross Breeding, In: Proceedings Symposium of the Analysis ofMolecular Data, August 1994, Crop Science Society of America, Corvallis,Oreg., where it is demonstrated that a backcross conversion can be madein as few as two backcrosses.

The complexity of the backcross conversion method depends on the type oftrait being transferred (single genes or closely linked genes as vs.unlinked genes), the level of expression of the trait, the type ofinheritance (cytoplasmic or nuclear) and the types of parents includedin the cross. It is understood by those of ordinary skill in the artthat for single gene traits that are relatively easy to classify, thebackcross method is effective and relatively easy to manage. (SeeHallauer et al. in Corn and Corn Improvement, Sprague and Dudley, ThirdEd. 1998). Desired traits that may be transferred through backcrossconversion include, but are not limited to, waxy starch, sterility(nuclear and cytoplasmic), fertility restoration, grain color (white),nutritional enhancements, drought resistance, enhanced nitrogenutilization efficiency, altered nitrogen responsiveness, altered fattyacid profile, increased digestibility, low phytate, industrialenhancements, disease resistance (bacterial, fungal or viral), insectresistance, herbicide resistance and yield enhancements. In addition, anintrogression site itself, such as an FRT site, Lox site or other sitespecific integration site, may be inserted by backcrossing and utilizedfor direct insertion of one or more genes of interest into a specificplant variety. In some embodiments of the invention, the number of locithat may be backcrossed into PHF1J is at least 1, 2, 3, 4, or 5 and/orno more than 6, 5, 4, 3, or 2. A single loci may contain severaltransgenes, such as a transgene for disease resistance that, in the sameexpression vector, also contains a transgene for herbicide resistance.The gene for herbicide resistance may be used as a selectable markerand/or as a phenotypic trait. A single locus conversion of site specificintegration system allows for the integration of multiple genes at theconverted loci. Further, SSI and FRT technologies known to those ofskill in the art in the art may result in multiple gene introgressionsat a single locus.

The backcross conversion may result from either the transfer of adominant allele or a recessive allele. Selection of progeny containingthe trait of interest is accomplished by direct selection for a traitassociated with a dominant allele. Transgenes transferred viabackcrossing typically function as a dominant single gene trait and arerelatively easy to classify. Selection of progeny for a trait that istransferred via a recessive allele, such as the waxy starchcharacteristic, requires growing and selfing the first backcrossgeneration to determine which plants carry the recessive alleles.Recessive traits may require additional progeny testing in successivebackcross generations to determine the presence of the locus ofinterest. The last backcross generation is usually selfed to give purebreeding progeny for the gene(s) being transferred, although a backcrossconversion with a stably introgressed trait may also be maintained byfurther backcrossing to the recurrent parent with selection for theconverted trait.

Along with selection for the trait of interest, progeny are selected forthe phenotype of the recurrent parent. While occasionally additionalpolynucleotide sequences or genes may be transferred along with thebackcross conversion, the backcross conversion line “fits into the samehybrid combination as the recurrent parent inbred line and contributesthe effect of the additional gene added through the backcross.” Poehlmanet al. (1995, page 334). It has been proposed that in general thereshould be at least four backcrosses when it is important that therecovered lines be essentially identical to the recurrent parent exceptfor the characteristic being transferred (Fehr 1987, Principles ofCultivar Development). However, as noted above, the number ofbackcrosses necessary can be reduced with the use of molecular markers.Other factors, such as a genetically similar donor parent, may alsoreduce the number of backcrosses necessary.

One process for adding or modifying a trait or locus in maize inbredline PHF1J comprises crossing PHF1J plants grown from PHF1J seed withplants of another maize line that comprise the desired trait or locus,selecting F1 progeny plants that comprise the desired trait or locus toproduce selected F1 progeny plants, crossing the selected progeny plantswith the PHF1J plants to produce backcross progeny plants, selecting forbackcross progeny plants that have the desired trait or locus and themorphological characteristics of maize inbred line PHF1J to produceselected backcross progeny plants; and backcrossing to PHF1J three ormore times in succession to produce selected fourth or higher backcrossprogeny plants that comprise said trait or locus. The modified PHF1J maybe further characterized as having the physiological and morphologicalcharacteristics of maize inbred line PHF1J listed in Table 1 asdetermined at the 5% significance level when grown in the sameenvironmental conditions and/or may be characterized by percentsimilarity or identity to PHF1J as determined by SSR markers. The abovemethod may be utilized with fewer backcrosses in appropriate situations,such as when the donor parent is highly related or markers are used inthe selection step. Desired traits that may be used include thosenucleic acids known in the art, some of which are listed herein, thatwill affect traits through nucleic acid expression or inhibition.Desired loci include the introgression of FRT, Lox and other sites forsite specific integration.

In addition, the above process and other similar processes describedherein may be used to produce F1 hybrid maize seed by adding a step atthe end of the process that comprises crossing PHF1J with theintrogressed trait or locus with a different maize plant and harvestingthe resultant F1 hybrid maize seed.

Male Sterility and Hybrid Seed Production

Hybrid seed production requires elimination or inactivation of pollenproduced by the female inbred parent. Incomplete removal or inactivationof the pollen provides the potential for self-pollination. A reliablemethod of controlling male fertility in plants offers the opportunityfor improved seed production.

PHF1J can be produced in a male-sterile form. There are several ways inwhich a maize plant can be manipulated so that it is male sterile. Theseinclude use of manual or mechanical emasculation (or detasseling), useof one or more genetic factors that confer male sterility, includingcytoplasmic genetic and/or nuclear genetic male sterility, use ofgametocides and the like. A male sterile inbred designated PHF1J mayinclude one or more genetic factors, which result in cytoplasmic geneticand/or nuclear genetic male sterility. All of such embodiments arewithin the scope of the present claims. The male sterility may be eitherpartial or complete male sterility.

Hybrid maize seed is often produced by a male sterility systemincorporating manual or mechanical detasseling. Alternate strips of twomaize inbreds are planted in a field, and the pollen-bearing tassels areremoved from one of the inbreds (female). Provided that there issufficient isolation from sources of foreign maize pollen, the ears ofthe detasseled inbred will be fertilized only from the other inbred(male), and the resulting seed is therefore hybrid and will form hybridplants.

The laborious detasseling process can be avoided by using cytoplasmicmale-sterile (CMS) inbreds. Plants of a CMS inbred are male sterile as aresult of genetic factors in the cytoplasm, as opposed to the nucleus,and so nuclear linked genes are not transferred during backcrossing.Thus, this characteristic is inherited exclusively through the femaleparent in maize plants, since only the female provides cytoplasm to thefertilized seed. CMS plants are fertilized with pollen from anotherinbred that is not male-sterile. Pollen from the second inbred may ormay not contribute genes that make the hybrid plants male-fertile, andeither option may be preferred depending on the intended use of thehybrid. The same hybrid seed, a portion produced from detasseled fertilemaize and a portion produced using the CMS system, can be blended toinsure that adequate pollen loads are available for fertilization whenthe hybrid plants are grown. CMS systems have been successfully usedsince the 1950's, and the male sterility trait is routinely backcrossedinto inbred lines. See Wych, p. 585-586,1998.

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

These, and the other methods of conferring genetic male sterility in theart, each possess their own benefits and drawbacks. Some other methodsuse a variety of approaches such as delivering into the plant a geneencoding a cytotoxic substance associated with a male tissue specificpromoter or an antisense system in which a gene critical to fertility isidentified and an antisense to that gene is inserted in the plant (seeFabinjanski, et al. EPO 89/3010153.8 publication no. 329,308 and PCTapplication PCT/CA90/00037 published as WO 90/08828).

Another system for controlling male sterility makes use of gametocides.Gametocides are not a genetic system, but rather a topical applicationof chemicals. These chemicals affect cells that are critical to malefertility. The application of these chemicals affects fertility in theplants only for the growing season in which the gametocide is applied(see Carlson, Glenn R., U.S. Pat. No. 4,936,904). Application of thegametocide, timing of the application and genotype specificity oftenlimit the usefulness of the approach and it is not appropriate in allsituations.

Incomplete control over male fertility may result in self-pollinatedseed being unintentionally harvested and packaged with hybrid seed. Thiswould typically be only female parent seed, because the male plant isgrown in rows that are typically destroyed prior to seed development.Once the seed from the hybrid bag is planted, it is possible to identifyand select these self-pollinated plants. These self-pollinated plantswill be one of the inbred lines used to produce the hybrid. Though thepossibility of inbred PHF1J being included in a hybrid seed bag exists,the occurrence is very low because much care is taken by seed companiesto avoid such inclusions. It is worth noting that hybrid seed is sold togrowers for the production of grain or forage and not for breeding orseed production. These self-pollinated plants can be identified andselected by one skilled in the art due to their less vigorous appearancefor vegetative and/or reproductive characteristics, including shorterplant height, small ear size, ear and kernel shape, cob color, or othercharacteristics.

Identification of these self-pollinated lines can also be accomplishedthrough molecular marker analyses. See, “The Identification of FemaleSelfs in Hybrid Maize: A Comparison Using Electrophoresis andMorphology”, Smith, J. S. C. and Wych, R. D., Seed Science andTechnology 14, 1-8 (1995), the disclosure of which is expresslyincorporated herein by reference. Through these technologies, thehomozygosity of the self pollinated line can be verified by analyzingallelic composition at various loci along the genome. Those methodsallow for rapid identification of the invention disclosed herein. Seealso, “Identification of Atypical Plants in Hybrid Maize Seed byPostcontrol and Electrophoresis” Sarca, V. et al., Probleme de GeneticaTeoritica si Aplicata Vol. 20(1) p. 29-42.

An embodiment of this invention is a process for producing seed of PHF1Jcomprising planting a collection of seed comprising seed of a hybrid,one of whose parents is inbred PHF1J said collection also comprisingseed of said inbred, growing plants from said collection of seed,identifying inbred parent plants, selecting said inbred parent plant;and controlling pollination to preserve the homozygosity of said inbredparent plant.

Transformation

The advent of new molecular biological techniques has allowed theisolation and characterization of genetic elements with specificfunctions, such as encoding specific protein products. Scientists in thefield of plant biology developed a strong interest in engineering thegenome of plants to contain and express foreign genetic elements, oradditional, or modified versions of native or endogenous geneticelements in order to alter the traits of a plant in a specific manner.Any DNA sequences, whether from a different species or from the samespecies, which are inserted into the genome using transformation arereferred to herein collectively as “transgenes”. In some embodiments ofthe invention, a transformed variant of PHF1J may contain at least onetransgene but could contain at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10and/or no more than 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, or 2.Over the last fifteen to twenty years several methods for producingtransgenic plants have been developed, and the present invention alsorelates to transformed versions of the claimed inbred maize line PHF1Jas well as hybrid combinations thereof.

Numerous methods for plant transformation have been developed, includingbiological and physical plant transformation protocols. See, forexample, Miki et al., “Procedures for Introducing Foreign DNA intoPlants” in Methods in Plant Molecular Biology and Biotechnology, Glick,B. R. and Thompson, J. E. Eds. (CRC Press, Inc., Boca Raton, 1993) pages67-88 and Armstrong, “The First Decade of Maize Transformation: A Reviewand Future Perspective” (Maydica 44:101-109, 1999). In addition,expression vectors and in vitro culture methods for plant cell or tissuetransformation and regeneration of plants are available. See, forexample, Gruber et al., “Vectors for Plant Transformation” in Methods inPlant Molecular Biology and Biotechnology, Glick, B. R. and Thompson, J.E. Eds.

The most prevalent types of plant transformation involve theconstruction of an expression vector. Such a vector comprises a DNAsequence that contains a gene under the control of or operatively linkedto a regulatory element, for example a promoter. The vector may containone or more genes and one or more regulatory elements.

A genetic trait which has been engineered into the genome of aparticular maize plant using transformation techniques, could be movedinto the genome of another line using traditional breeding techniquesthat are well known in the plant breeding arts. For example, abackcrossing approach is commonly used to move a transgene from atransformed maize plant to an elite inbred line, and the resultingprogeny would then comprise the transgene(s). Also, if an inbred linewas used for the transformation then the transgenic plants could becrossed to a different inbred in order to produce a transgenic hybridmaize plant.

Various genetic elements can be introduced into the plant genome usingtransformation. These elements include, but are not limited to genes;coding sequences; inducible, constitutive, and tissue specificpromoters; enhancing sequences; and signal and targeting sequences. Forexample, see the traits, genes and transformation methods listed in U.S.Pat. Nos. 6,118,055 and 6,284,953, which are herein incorporated byreference. In addition, transformability of a line can be increased byintrogressing the trait of high transformability from another line knownto have high transformability, such as Hi-II. See U.S. PatentApplication Publication US2004/0016030 (2004).

With transgenic plants according to the present invention, a foreignprotein can be produced in commercial quantities. Thus, techniques forthe selection and propagation of transformed plants, which are wellunderstood in the art, yield a plurality of transgenic plants that areharvested in a conventional manner, and a foreign protein then can beextracted from a tissue of interest or from total biomass. Proteinextraction from plant biomass can be accomplished by known methods whichare discussed, for example, by Heney and Orr, Anal. Biochem. 114: 92-6(1981).

A genetic map can be generated, primarily via conventional RestrictionFragment Length Polymorphisms (RFLP), Polymerase Chain Reaction (PCR)analysis, Simple Sequence Repeats (SSR) and Single NucleotidePolymorphisms (SNP) that identifies the approximate chromosomal locationof the integrated DNA molecule. For exemplary methodologies in thisregard, see Glick and Thompson, Methods in Plant Molecular Biology andBiotechnology 269-284 (CRC Press, Boca Raton,1993).

Wang et al. discuss “Large Scale Identification, Mapping and Genotypingof Single-Nucleotide Polymorphisms in the Human Genome”, Science,280:1077-1082, 1998, and similar capabilities are available for the corngenome. Map information concerning chromosomal location is useful forproprietary protection of a subject transgenic plant. If unauthorizedpropagation is undertaken and crosses made with other germplasm, the mapof the integration region can be compared to similar maps for suspectplants to determine if the latter have a common parentage with thesubject plant. Map comparisons would involve hybridizations, RFLP, PCR,SSR and sequencing, all of which are conventional techniques. SNPs mayalso be used alone or in combination with other techniques.

Likewise, by means of the present invention, plants can be geneticallyengineered to express various phenotypes of agronomic interest. Throughthe transformation of maize the expression of genes can be altered toenhance disease resistance, insect resistance, herbicide resistance,agronomic traits, grain quality and other traits. Transformation canalso be used to insert DNA sequences which control or help controlmale-sterility. DNA sequences native to maize as well as non-native DNAsequences can be transformed into maize and used to alter levels ofnative or non-native proteins. Various promoters, targeting sequences,enhancing sequences, and other DNA sequences can be inserted into themaize genome for the purpose of altering the expression of proteins.Reduction of the activity of specific genes (also known as genesilencing, or gene suppression) is desirable for several aspects ofgenetic engineering in plants.

Many techniques for gene silencing are well known to one of skill in theart, including but not limited to knock-outs (such as by insertion of atransposable element such as mu (Vicki Chandler, The Maize Handbook ch.118 (Springer-Verlag 1994) or other genetic elements such as a FRT, Loxor other site specific integration site, antisense technology (see,e.g., Sheehy et al.

No. 6,232,529 (method of producing high oil seed bymodification of starch levels (AGP)). The fatty acid modification genesmentioned above may also be used to affect starch content and/orcomposition through the interrelationship of the starch and oilpathways.

(D) Altered antioxidant content or composition, such as alteration oftocopherol or tocotrienols. For example, see U.S. Pat.

4. Genes that Control Male-Sterility

There are several methods of conferring genetic male sterilityavailable, such as multiple mutant genes at separate locations withinthe genome that confer male sterility, as disclosed in U.S. Pat. Nos.4,654,465 and 4,727,219 to Brar et al. and chromosomal translocations asdescribed by Patterson in U.S. Pat. Nos. 3,861,709 and 3,710,511. Inaddition to these methods, Albertsen et al., U.S. Pat. No. 5,432,068,describe a system of nuclear male sterility which includes: identifyinga gene which is critical to male fertility; silencing this native genewhich is critical to male fertility; removing the native promoter fromthe essential male fertility gene and replacing it with an induciblepromoter; inserting this genetically engineered gene back into theplant; and thus creating a plant that is male sterile because theinducible promoter is not “on” resulting in the male fertility gene notbeing transcribed. Fertility is restored by inducing, or turning “on”,the promoter, which in turn allows the gene that confers male fertilityto be transcribed.

Using PHF1J to Develop Other Maize Inbreds

Inbred maize lines such as PHF1J are typically developed for use in theproduction of hybrid maize lines. However, inbred lines such as PHF1Jalso provide a source of breeding material that may be used to developnew maize inbred lines. Plant breeding techniques known in the art andused in a maize plant breeding program include, but are not limited to,recurrent selection, mass selection, bulk selection, mass selection,backcrossing, pedigree breeding, open pollination breeding, restrictionfragment length polymorphism enhanced selection, genetic marker enhancedselection, making double haploids, and transformation. Oftencombinations of these techniques are used. The development of maizehybrids in a maize plant breeding program requires, in general, thedevelopment of homozygous inbred lines, the crossing of these lines, andthe evaluation of the crosses. There are many analytical methodsavailable to evaluate the result of a cross. The oldest and mosttraditional method of analysis is the observation of phenotypic traitsbut genotypic analysis may also be used.

Using PHF1J in a Breeding Program

This invention is directed to methods for producing a maize plant bycrossing a first parent maize plant with a second parent maize plantwherein either the first or second parent maize plant is an inbred maizeplant of the line PHF1J. The other parent may be any other maize plant,such as another inbred line or a plant that is part of a synthetic ornatural population. Any such methods using the inbred maize line PHF1Jare part of this invention: selfing, sibbing, backcrosses, massselection, pedigree breeding, bulk selection, hybrid production, crossesto populations, and the like. These methods are well known in the artand some of the more commonly used breeding methods are described below.Descriptions of breeding methods can also be found in one of severalreference books (e.g., Allard, Principles of Plant Breeding, 1960;Simmonds, Principles of Crop Improvement, 1979; Fehr, “Breeding Methodsfor Cultivar Development”, Production and Uses, 2^(nd) ed., Wilcoxeditor, 1987 the disclosure of which is incorporated herein byreference).

Pedigree Breeding

Pedigree breeding starts with the crossing of two genotypes, such asPHF1J and one other elite inbred line having one or more desirablecharacteristics that is lacking or which complements PHF1J. If the twooriginal parents do not provide all the desired characteristics, othersources can be included in the breeding population. In the pedigreemethod, superior plants are selfed and selected in successive filialgenerations. In the succeeding filial generations the heterozygouscondition gives way to homogeneous lines as a result of self-pollinationand selection. Typically in the pedigree method of breeding, five ormore successive filial generations of selfing and selection ispracticed: F1→F2; F2→F3; F3→F4; F4→F5, etc. After a sufficient amount ofinbreeding, successive filial generations will serve to increase seed ofthe developed inbred. Preferably, the inbred line comprises homozygousalleles at about 95% or more of its loci.

In addition to being used to create a backcross conversion, backcrossingcan also be used in combination with pedigree breeding to modify PHF1Jand a hybrid that is made using the modified PHF1J. As discussedpreviously, backcrossing can be used to transfer one or morespecifically desirable traits from one line, the donor parent, to aninbred called the recurrent parent, which has overall good agronomiccharacteristics yet lacks that desirable trait or traits. However, thesame procedure can be used to move the progeny toward the genotype ofthe recurrent parent but at the same time retain many components of thenon-recurrent parent by stopping the backcrossing at an early stage andproceeding with selfing and selection. For example, an F1, such as acommercial hybrid, is created. This commercial hybrid may be backcrossedto one of its parent lines to create a BC1 or BC2. Progeny are selfedand selected so that the newly developed inbred has many of theattributes of the recurrent parent and yet several of the desiredattributes of the non-recurrent parent. This approach leverages thevalue and strengths of the recurrent parent for use in new hybrids andbreeding.

Therefore, an embodiment of this invention is a method of making abackcross conversion of maize inbred line PHF1J, comprising the steps ofcrossing a plant of maize inbred line PHF1J with a donor plantcomprising a mutant gene or transgene conferring a desired trait,selecting an F1 progeny plant comprising the mutant gene or transgeneconferring the desired trait, and backcrossing the selected F1 progenyplant to a plant of maize inbred line PHF1J. This method may furthercomprise the step of obtaining a molecular marker profile of maizeinbred line PHF1J and using the molecular marker profile to select for aprogeny plant with the desired trait and the molecular marker profile ofPHF1J. In the same manner, this method may be used to produce an F1hybrid seed by adding a final step of crossing the desired traitconversion of maize inbred line PHF1J with a different maize plant tomake F1 hybrid maize seed comprising a mutant gene or transgeneconferring the desired trait.

Recurrent Selection and Mass Selection

Recurrent selection is a method used in a plant breeding program toimprove a population of plants. PHF1J is suitable for use in a recurrentselection program. The method entails individual plants crosspollinating with each other to form progeny. The progeny are grown andthe superior progeny selected by any number of selection methods, whichinclude individual plant, half-sib progeny, full-sib progeny, selfedprogeny and topcrossing. The selected progeny are cross pollinated witheach other to form progeny for another population. This population isplanted and again superior plants are selected to cross pollinate witheach other. Recurrent selection is a cyclical process and therefore canbe repeated as many times as desired. The objective of recurrentselection is to improve the traits of a population. The improvedpopulation can then be used as a source of breeding material to obtaininbred lines to be used in hybrids or used as parents for a syntheticcultivar. A synthetic cultivar is the resultant progeny formed by theintercrossing of several selected inbreds.

Mass selection is a useful technique when used in conjunction withmolecular marker enhanced selection. In mass selection seeds fromindividuals are selected based on phenotype and/or genotype. Theseselected seeds are then bulked and used to grow the next generation.Bulk selection requires growing a population of plants in a bulk plot,allowing the plants to self-pollinate, harvesting the seed in bulk andthen using a sample of the seed harvested in bulk to plant the nextgeneration. Instead of self pollination, directed pollination could beused as part of the breeding program.

Mutation Breeding

Mutation breeding is one of many methods that could be used to introducenew traits into PHF1J. Mutations that occur spontaneously or areartificially induced can be useful sources of variability for a plantbreeder. The goal of artificial mutagenesis is to increase the rate ofmutation for a desired characteristic. Mutation rates can be increasedby many different means including temperature, long-term seed storage,tissue culture conditions, radiation; such as X-rays, Gamma rays (e.g.cobalt 60 or cesium 137), neutrons, (product of nuclear fission byuranium 235 in an atomic reactor), Beta radiation (emitted fromradioisotopes such as phosphorus 32 or carbon 14), or ultravioletradiation (preferably from 2500 to 2900 nm), or chemical mutagens (suchas base analogues (5-bromo-uracil), related compounds (8-ethoxycaffeine), antibiotics (streptonigrin), alkylating agents (sulfurmustards, nitrogen mustards, epoxides, ethylenamines, sulfates,sulfonates, sulfones, lactones), azide, hydroxylamine, nitrous acid, oracridines. Once a desired trait is observed through mutagenesis thetrait may then be incorporated into existing germplasm by traditionalbreeding techniques, such as backcrossing. Details of mutation breedingcan be found in “Principles of Cultivar Development” Fehr, 1993Macmillan Publishing Company, the disclosure of which is incorporatedherein by reference. In addition, mutations created in other lines maybe used to produce a backcross conversion of PHF1J that comprises suchmutation.

Breeding with Molecular Markers

Molecular markers, which includes markers identified through the use oftechniques such as Isozyme Electrophoresis, Restriction Fragment LengthPolymorphisms (RFLPs), Randomly Amplified Polymorphic DNAs (RAPDs),Arbitrarily Primed Polymerase Chain Reaction (AP-PCR), DNA AmplificationFingerprinting (DAF), Sequence Characterized Amplified Regions (SCARs),Amplified Fragment Length Polymorphisms (AFLPs), Simple Sequence Repeats(SSRs) and Single Nucleotide Polymorphisms (SNPs), may be used in plantbreeding methods utilizing PHF1J.

Isozyme Electrophoresis and RFLPs as discussed in Lee, M., “Inbred Linesof Maize and Their Molecular Markers,” The Maize Handbook,(Springer-Verlag, New York, Inc. 1994, at 423-432), have been widelyused to determine genetic composition. Isozyme Electrophoresis has arelatively low number of available markers and a low number of allelicvariants among maize inbreds. RFLPs allow more discrimination becausethey have a higher degree of allelic variation in maize and a largernumber of markers can be found. Both of these methods have been eclipsedby SSRs as discussed in Smith et al., “An evaluation of the utility ofSSR loci as molecular markers in maize (Zea mays L.): comparisons withdata from RFLPs and pedigree”, Theoretical and Applied Genetics (1997)vol. 95 at 163-173 and by Pejic et al., “Comparative analysis of geneticsimilarity among maize inbreds detected by RFLPs, RAPDs, SSRs, andAFLPs,” Theoretical and Applied Genetics (1998) at 1248-1255incorporated herein by reference. SSR technology is more efficient andpractical to use than RFLPs; more marker loci can be routinely used andmore alleles per marker locus can be found using SSRs in comparison toRFLPs. Single Nucleotide Polymorphisms may also be used to identify theunique genetic composition of the invention and progeny lines retainingthat unique genetic composition. Various molecular marker techniques maybe used in combination to enhance overall resolution.

Maize DNA molecular marker linkage maps have been rapidly constructedand widely implemented in genetic studies. One such study is describedin Boppenmaier, et al., “Comparisons among strains of inbreds forRFLPs”, Maize Genetics Cooperative Newsletter, 65:1991, pg. 90, isincorporated herein by reference.

One use of molecular markers is Quantitative Trait Loci (QTL) mapping.QTL mapping is the use of markers, which are known to be closely linkedto alleles that have measurable effects on a quantitative trait.Selection in the breeding process is based upon the accumulation ofmarkers linked to the positive effecting alleles and/or the eliminationof the markers linked to the negative effecting alleles from the plant'sgenome.

Molecular markers can also be used during the breeding process for theselection of qualitative traits. For example, markers closely linked toalleles or markers containing sequences within the actual alleles ofinterest can be used to select plants that contain the alleles ofinterest during a backcrossing breeding program. The markers can also beused to select for the genome of the recurrent parent and against thegenome of the donor parent. Using this procedure can minimize the amountof genome from the donor parent that remains in the selected plants. Itcan also be used to reduce the number of crosses back to the recurrentparent needed in a backcrossing program. The use of molecular markers inthe selection process is often called genetic marker enhanced selection.

Production of Double Haploids

The production of double haploids can also be used for the developmentof inbreds in the breeding program. For example, an F1 hybrid for whichPHF1J is a parent can be used to produce double haploid plants. Doublehaploids are produced by the doubling of a set of chromosomes (1 N) froma heterozygous plant to produce a completely homozygous individual. Forexample, see Wan et al., “Efficient Production of Doubled Haploid PlantsThrough Colchicine Treatment of Anther-Derived Maize Callus”,Theoretical and Applied Genetics, 77:889-892, 1989 and US2003/0005479.This can be advantageous because the process omits the generations ofselfing needed to obtain a homozygous plant from a heterozygous source.

Haploid induction systems have been developed for various plants toproduce haploid tissues, plants and seeds. The haploid induction systemcan produce haploid plants from any genotype by crossing a selected line(as female) with an inducer line. Such inducer lines for maize includeStock 6 (Coe, 1959, Am. Nat. 93:381-382; Sharkar and Coe, 1966, Genetics54:453-464) RWS (see world wide web sitewww.uni-hohenheim.de/%7Eipspwww/350b/indexe.html#Project3), KEMS(Deimling, Roeber, and Geiger, 1997, Vortr. Pflanzenzuchtg38:203-224),or KMS and ZMS (Chalyk, Bylich & Chebotar, 1994, MNL 68:47; Chalyk &Chebotar, 2000, Plant Breeding 119:363-364), and indeterminategametophyte (ig) mutation (Kermicle 1969 Science 166:1422-1424).

Thus, an embodiment of this invention is a process for making asubstantially homozygous PHF1J progeny plant by producing or obtaining aseed from the cross of PHF1J and another maize plant and applying doublehaploid methods to the F1 seed or F1 plant or to any successive filialgeneration. Such methods decrease the number of generations required toproduce an inbred with similar genetics or characteristics to PHF1J. SeeBernardo, R. and Kahler, A. L., Theor. Appl. Genet. 102:986-992, 2001.

In particular, a process of making seed retaining the molecular markerprofile of maize inbred line PHF1J is contemplated, such processcomprising obtaining or producing F1 hybrid seed for which maize inbredline PHF1J is a parent, inducing doubled haploids to create progenywithout the occurrence of meiotic segregation, obtaining the molecularmarker profile of maize inbred line PHF1J, and selecting progeny thatretain the molecular marker profile of PHF1J.

Use of PHF1J in Tissue Culture

This invention is also directed to the use of PHF1J in tissue culture.As used herein, the term “tissue culture” includes plant protoplasts,plant cell tissue culture, cultured microspores, plant calli, plantclumps, and the like. As used herein, phrases such as “growing the seed”or “grown from the seed” include embryo rescue, isolation of cells fromseed for use in tissue culture, as well as traditional growing methods.

Duncan, Williams, Zehr, and Widholm, Planta (1985) 165:322-332 reflectsthat 97% of the plants cultured that produced callus were capable ofplant regeneration. Subsequent experiments with both inbreds and hybridsproduced 91% regenerable callus that produced plants. In a further studyin 1988, Songstad, Duncan & Widholm in Plant Cell Reports (1988),7:262-265 reports several media additions that enhance regenerability ofcallus of two inbred lines. Other published reports also indicated that“nontraditional” tissues are capable of producing somatic embryogenesisand plant regeneration. K. P. Rao, et al., Maize Genetics CooperationNewsletter, 60:64-65 (1986), refers to somatic embryogenesis from glumecallus cultures and B. V. Conger, et al., Plant Cell Reports, 6:345-347(1987) indicates somatic embryogenesis from the tissue cultures of maizeleaf segments. Thus, it is clear from the literature that the state ofthe art is such that these methods of obtaining plants are, and were,“conventional” in the sense that they are routinely used and have a veryhigh rate of success.

Tissue culture of maize, including tassel/anther culture, is describedin U.S. 2002/0062506A1 and European Patent Application, publicationEP0160,390, each of which are incorporated herein by reference for thispurpose. Maize tissue culture procedures are also described in Green andRhodes, “Plant Regeneration in Tissue Culture of Maize,” Maize forBiological Research (Plant Molecular Biology Association,Charlottesville, Virginia 1982, at 367-372) and in Duncan, et al., “TheProduction of Callus Capable of Plant Regeneration from Immature Embryosof Numerous Zea Mays Genotypes,” 165 Planta 322-332 (1985). Thus,another aspect of this invention is to provide cells which upon growthand differentiation produce maize plants having the genotype and/orphysiological and morphological characteristics of inbred line PHF1J.

Progeny Plants

All plants produced by the use of the methods described herein and thatretain the unique genetic or trait combinations of PHF1J are within thescope of the invention. Progeny of the breeding methods described hereinmay be characterized in any number of ways, such as by traits retainedin the progeny, pedigree and/or molecular markers. Combinations of thesemethods of characterization may be used.

Breeder's of ordinary skill in the art have developed the concept of an“essentially derived variety”, which is defined in 7 U.S.C. § 2104(a)(3)of the Plant Variety Protection Act and is hereby incorporated byreference. Varieties and plants that are essentially derived from PHF1Jare within the scope of the invention.

Pedigree is a method used by breeders of ordinary skill in the art todescribe the varieties. Varieties that are more closely related bypedigree are likely to share common genotypes and combinations ofphenotypic characteristics. All breeders of ordinary skill in the artmaintain pedigree records of their breeding programs. These pedigreerecords contain a detailed description of the breeding process,including a listing of all parental lines used in the breeding processand information on how such line was used. One embodiment of thisinvention is progeny plants and parts thereof with at least one ancestorthat is PHF1J, and more specifically, where the pedigree of the progenyincludes 1, 2, 3, 4, and/or 5 or less breeding crosses to a maize plantother than PHF1J or a plant that has PHF1J as a parent or otherprogenitor. A breeder of ordinary skill in the art would know if PHF1Jwere used in the development of a progeny line, and would also know howmany crosses to a line other than PHF1J or line with PHF1J as a parentor other progenitor were made in the development of any progeny line.

Molecular markers also provide a means by which those of ordinary skillin the art characterize the similarity or differences of two lines.Using the breeding methods described herein, one can develop individualplants, plant cells, and populations of plants that retain at least 25%,30%, 35%, 40%, 45%, 50%, 55%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%,68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%,82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%,96%, 97%, 98%, 99% or 99.5% genetic contribution from inbred line PHF1J,as measured by either percent identity or percent similarity. On average50% of the starting germplasm would be expected to be passed to theprogeny line after one cross to another line, 25% after another cross toa different line, and so on. With backcrossing, the expectedcontribution of PHF1J after 2, 3, 4 and 5 doses (or 1, 2, 3 and 4backcrosses) would be 75%, 87.5%, 93.75% and 96.875% respectively.Actual genetic contribution may be much higher than the geneticcontribution expected by pedigree, especially if molecular markers areused in selection. Molecular markers could also be used to confirmand/or determine the pedigree of the progeny line.

Traits are also used by those of ordinary skill in the art tocharacterize progeny. Traits are commonly evaluated at a significancelevel, such as a 1%, 5% or 10% significance level, when measured inplants grown in the same environmental conditions. For example, abackcross conversion of PHF1J may be characterized as having the samemorphological and physiological traits as PHF1J. The traits used forcomparison may be those traits shown in Table 1, Table 3, Table 4 orTable 5.

A breeder will commonly work to combine a specific trait of anundeveloped variety of the species, such as a high level of resistanceto a particular disease, with one or more of the elite agronomiccharacteristics (yield, maturity, plant size, lodging resistance, etc.)needed for use as a commercial variety. This combination, oncedeveloped, provides a valuable source of new germplasm for furtherbreeding. For example, it may take 10-15 years and significant effort toproduce such a combination, yet progeny may be developed that retainthis combination in as little as 2-5 years and with much less effort.

SPECIFIC EMBODIMENTS

Specific methods and products produced using inbred line PHF1J in plantbreeding are discussed in the following sections. The methods outlinedare described in detail by way of illustration and example for purposesof clarity and understanding. However, it will be obvious that certainchanges and modifications may be practiced within the scope of theinvention.

One method for producing a line derived from inbred line PHF1J is asfollows. One of ordinary skill in the art would produce or obtain a seedfrom the cross between inbred line PHF1J and another variety of maize,such as an elite inbred variety. The F1 seed derived from this crosswould be grown to form a homogeneous population. The F1 seed wouldcontain essentially all of the alleles from variety PHF1J andessentially all of the alleles from the other maize variety. The F1nuclear genome would be made-up of 50% variety PHF1J and 50% of theother elite variety. The F1 seed would be grown and allowed to self,thereby forming F2 seed. On average the F2 seed would have derived 50%of its alleles from variety PHF1J and 50% from the other maize variety,but many individual plants from the population would have a greaterpercentage of their alleles derived from PHF1J (Wang J. and R. Bernardo,2000, Crop Sci. 40:659-665 and Bernardo, R. and A. L. Kahler, 2001,Theor. Appl. Genet. 102:986-992). The molecular markers of PHF1J couldbe used to select and retain those lines with high similarity to PHF1J.The F2 seed would be grown and selection of plants would be made basedon visual observation, markers and/or measurement of traits. The traitsused for selection may be any PHF1J trait described in thisspecification, including the inbred per se maize PHF1J traits describedherein under the detailed description of inbred PHF1J. Such traits mayalso be the good general or specific combining ability of PHF1J,including its ability to produce hybrids with the approximate maturityand/or hybrid combination traits described herein under the detaileddescription of inbred PHF1J. The PHF1J progeny plants that exhibit oneor more of the desired PHF1J traits, such as those listed herein, wouldbe selected and each plant would be harvested separately. This F3 seedfrom each plant would be grown in individual rows and allowed to self.Then selected rows or plants from the rows would be harvestedindividually. The selections would again be based on visual observation,markers and/or measurements for desirable traits of the plants, such asone or more of the desirable PHF1J traits listed herein. The process ofgrowing and selection would be repeated any number of times until aPHF1J progeny inbred plant is obtained. The PHF1J progeny inbred plantwould contain desirable traits derived from inbred plant PHF1J, some ofwhich may not have been expressed by the other maize variety to whichinbred line PHF1J was crossed and some of which may have been expressedby both maize varieties but now would be at a level equal to or greaterthan the level expressed in inbred variety PHF1J. However, in each casethe resulting progeny line would benefit from the efforts of theinventor(s), and would not have existed but for the inventor(s) work increating PHF1J. The PHF1J progeny inbred plants would have, on average,50% of their nuclear genes derived from inbred line PHF1J, but manyindividual plants from the population would have a greater percentage oftheir alleles derived from PHF1J. This breeding cycle, of crossing andselfing, and optional selection, may be repeated to produce anotherpopulation of PHF1J progeny maize plants with, on average, 25% of theirnuclear genes derived from inbred line PHF1J, but, again, manyindividual plants from the population would have a greater percentage oftheir alleles derived from PHF1J. This process can be repeated for athird, fourth, fifth, sixth, seventh or more breeding cycles. Anotherembodiment of the invention is a PHF1J progeny plant that has receivedthe desirable PHF1J traits listed herein through the use of PHF1J, whichtraits were not exhibited by other plants used in the breeding process.

Therefore, an embodiment of this invention is a PHF1J progeny maizeplant, wherein at least one ancestor of said PHF1J progeny maize plantis the maize plant or plant part of PHF1J, and wherein the pedigree ofsaid PHF1J progeny maize plant is within two breeding crosses of PHF1Jor a plant that has PHF1J as a parent. The progeny plants, parts andplant cells produced from PHF1J may be further characterized as having apercent marker similarity or identity with PHF1J as described herein.

The previous example can be modified in numerous ways, for instanceselection may or may not occur at every selfing generation, selectionmay occur before or after the actual self-pollination process occurs, orindividual selections may be made by harvesting individual ears, plants,rows or plots at any point during the breeding process described. Doublehaploid breeding methods may be used at any step in the process. Insteadof selfing out of the hybrid produced from the inbred, one could firstcross the hybrid to either a parent line or a different inbred, and thenself out of that cross.

The population of plants produced at each and any cycle of breeding isalso an embodiment of the invention, and on average each such populationwould predictably consist of plants containing approximately 50% of itsgenes from inbred line PHF1J in the first breeding cycle, 25% of itsgenes from inbred line PHF1J in the second breeding cycle, 12.5% of itsgenes from inbred line PHF1J in the third breeding cycle, 6.25% in thefourth breeding cycle, 3.125% in the fifth breeding cycle, and so on.However, in each case the use of PHF1J provides a substantial benefit.The linkage groups of PHF1J would be retained in the progeny lines, andsince current estimates of the maize genome size is about 50,000-80,000genes (Xiaowu, Gai et al., Nucleic Acids Research, 2000, Vol. 28, No. 1,94-96), in addition to non-coding DNA that impacts gene expression, itprovides a significant advantage to use PHF1J as starting material toproduce a line that retains desired genetics or traits of PHF1J.

Therefore, an embodiment of the invention is a process for making apopulation of PHF1J progeny inbred maize plants comprising obtaining orproducing a first generation progeny maize seed comprising the plant ofPHF1J as a parent, growing said first generation progeny maize seed toproduce first generation maize plants and obtaining self or sibpollinated seed from said first generation maize plants, and growing theself or sib pollinated seed to obtain a population of PHF1J progenyinbred maize plants.

The population of PHF1J progeny inbred maize plants produced by thismethod are also embodiments of the invention, and such population as awhole will retain the expected genetic contribution of PHF1J. An inbredline selected from the population of PHF1J progeny inbred maize plantsproduced by this method is an embodiment, and such line may be furthercharacterized by its molecular marker identity or similarity to PHF1J.

In this manner, the invention also encompasses a process for making aPHF1J inbred progeny maize plant comprising the steps of obtaining orproducing a first generation progeny maize seed wherein a parent of saidfirst generation progeny maize seed is a PHF1J plant, growing said firstgeneration progeny maize seed to produce a first generation maize plantand obtaining self or sib pollinated seed from said first generationmaize plant, and producing successive filial generations to obtain aPHF1J inbred progeny maize plant. Also an embodiment of this inventionis the first breeding cycle inbred PHF1J maize plant produced by thismethod.

Crosses to Other Species

The utility of inbred maize line PHF1J also extends to crosses withother species. Commonly, suitable species will be of the familyGraminaceae, and especially of the genera Zea, Tripsacum, Coix,Schlerachne, Polytoca, Chionachne, and Trilobachne, of the tribeMaydeae. Potentially suitable for crosses with PHF1J may be the variousvarieties of grain sorghum, Sorghum bicolor (L.) Moench.

INDUSTRIAL APPLICABILITY

Maize is used as human food, livestock feed, and as raw material inindustry. The food uses of maize, in addition to human consumption ofmaize kernels, include both products of dry- and wet-milling industries.The principal products of maize dry milling are grits, meal and flour.The maize wet-milling industry can provide maize starch, maize syrups,and dextrose for food use. Maize oil is recovered from maize germ, whichis a by-product of both dry- and wet-milling industries.

Maize, including both grain and non-grain portions of the plant, is alsoused extensively as livestock feed, primarily for beef cattle, dairycattle, hogs, and poultry.

Industrial uses of maize include production of ethanol, maize starch inthe wet-milling industry and maize flour in the dry-milling industry.The industrial applications of maize starch and flour are based onfunctional properties, such as viscosity, film formation, adhesiveproperties, and ability to suspend particles. The maize starch and flourhave application in the paper and textile industries. Other industrialuses include applications in adhesives, building materials, foundrybinders, laundry starches, explosives, oil-well muds, and other miningapplications.

Plant parts other than the grain of maize are also used in industry: forexample, stalks and husks are made into paper and wallboard and cobs areused for fuel and to make charcoal.

The seed of inbred maize line PHF1J, the plant produced from the inbredseed, the hybrid maize plant produced from the crossing of the inbred,hybrid seed, and various parts of the hybrid maize plant and transgenicversions of the foregoing, can be utilized for human food, livestockfeed, and as a raw material in industry.
